Product Overview

Featuring a sealed 10 year battery and 10 year manufacturer's warranty, the UltraFire ULLH10RF heat alarm provides constant detection at all times without the cost of an electrician to install. Part of the wireless ULLRF series, these alarms can interlink with 14 other alarms throughout the house using radio-frequency so that all connected alarms activate if one of them detects a possible fire, warning all occupants to the emergency. Ideal for rooms regularly exposed to dust, steam, or fumes like kitchens and garages, where traditional smoke alarms would suffer false activations.

FAQs (3)
Q. Can I put my smoke alarm on the wall, or must it be mounted on the ceiling?

The best location to install your smoke alarm is in the centre of the ceiling rather than on the wall.

During a fire, smoke initially rises and then spreads horizontally. Placing the smoke alarm in the centre of your ceiling means that it is closest to all four points of your room. This ensures that you receive the earliest possible warning of a fire.

For more information, read our guide to positioning your smoke alarm and guide to which smoke alarms are best for each room.

Q. Can a wireless router interfere with radio interlinked alarms?

A wireless router is very unlikely to interfere with the signal of your radio interlinked smoke, heat or CO alarm as the RF signal is digitally coded.

Q. If the radio interlinking signal on one unit fails will the units still work as stand alone units.

Yes, should the radio interlinking signal fail the units will continue to sound independently should they detect a fire.

Eas to set up & install At the beginning I thought that the blue (3 x radio waves) were actually part of the device lid. This put me off initially
